Answer:
eight hundred four thousand six or eight hundred four thousand and six
Step-by-step explanation:
Add like terms
-4x+x=-3x
6-2=4
So the simplified term is 4-3x
The circumference= 186000000π miles and the speed or the earth is 7750000π miles per hour.
Step-by-step explanation:
Radius (r) = 93000000 miles
a) circumference= 2πr
= 2π(93000000) miles
= 186000000π miles
b) speed = distance / time
Here distance is the circumference and time is 24hrs because if the earth completes 1 revolution around the sun in 24hrs.
Speed = 186000000π/24
= 7750000π miles per hour
20p + 9t = 44.4
Subtract 9t from both sides:
20p = 44.4 - 9t
Divide both sides by 20:
p = 2.22 - 0.45t
1. false because it has only 2 triangular faces
2. true
3. true
4. i think its false, it has four
5.
